A Comparison of Military and Commercial Submersible Systems, Cost Environments, and Methods for Estimating Submersible Development and Production Costs
Models and Methods Track
The U.S. Navy and the U.S. Special Operations Forces (USSOCOM) have established requirements for wet and dry submersible vehicles capable of transporting combat teams and their equipments to and from the shoreline of enemy territory. The submersibles are carried to the vicinity of the enemy either by surface vessels or mounted upon the decks of fleet attack submarines. A recent high profile program, the Advanced Seal Delivery System (ASDS), was initiated to be the principal vehicle for performing this kind of mission. A fleet of as many as six or eight of the 55 ton units was planned. The program, however, encountered severe difficulties and cost overruns, and was terminated after the first unit was delivered. In recent years, a new commercial industry has emerged that develops and produces submersible systems for a variety of private and non-military government users. These uses include undersea tourism, recreational pursuits of the rich and famous, undersea archeology, fisheries management, environmental surveillance, mapping, and other purposes. The cost of these commercial submersible systems is reputed to be a fraction of typical NAVY developments, and this study documents and compares these cost differences. The U.S. Navy, after its ASDS experience, is interested in learning and applying any lessons that can be learned from the commercial operations, and thereby improving the affordability of its acquisition programs. To some extent, the NAVY may find that its normal development and oversight practices are at the center of its affordability problem, and some may need to be reformed or set aside. A product of this study is a parametric cost model for submersible systems. Although only a few (5) commercial programs were available for study, a substantial amount of information was conveyed to the study team by these companies. On the Government side, the ASDS was an important point of study and comparison but the Seal Delivery Vehicle (SDV), another NAVY submersible system, was also studied.
The study was conducted by the US Navy and MCR LLC. The detailed development and production commercial cost data was provided by two corporations interested in developing business opportunities with the Government. Techniques were developed to extrapolate and parse cost information into a standard MIL-STD-881B work breakdown structure. The costs were normalized to constant FY2010 dollars and combined with a common set of technical characteristics. Statistical analysis was used to create a family of cost estimating relationships (CERs) that could be combined to create a submersible cost model that provides estimates for government program environments, commercial program environments, and hybrid s program environments. Using these tools requires considerable informed judgment as well as a detailed knowledge of specific program plans and technical strategies. The study provides an estimating procedure and a rational approach to understanding and estimating conceptual submersible system costs. Further, a feature of the study was to advise NAVY program management of the likely costs for procuring a commercial submersible as available “off the shelf” or incorporating increasing levels of added military subsystem content and military optimization.
